Abstract

Provided is a technique capable of achieving high accuracy of patterning of an optical surface while suppressing complicated processing.
Production of a lens member (10, 10a) includes: a step of positioning a lens member (10, 10a) having a first surface, which is a convex optical surface, and a second surface, which is an optical surface facing the first surface, in a predetermined attitude; a step of recognizing surface shape data of the first surface using a dimensional measurement result of the first surface of the positioned lens member (10, 10a); and a step of irradiating the first surface of the lens member (10, 10a) with laser light to perform laser processing on the first surface, and controlling an irradiation position of the laser light based on the surface shape data.
